Pathologic N

This input is used for staging


**Note 1:** Involvement of inguinal, pelvic, or external iliac lymph nodes **WITHOUT** previous scrotal or inguinal surgery prior to presentation of the testis tumor is coded in M (distant metastasis), as distant lymph node involvement. **Note 2:** Size of the largest metastasis in a lymph node must be known to assign N. You may use a physician’s statement of the N category if this is the only information in the medical record. * If the size of the metastasis is not documented, determine the size of the largest involved lymph node as documented pathologically * If the size of the lymph node(s) cannot be determined, assign N1 * Do **not** code the size of any node(s) assigned in M (distant metastasis) **Regional lymph nodes** Aortic, NOS Lateral (lumbar) Para-aortic Periaortic Preaortic Retroaortic Pericaval, NOS Interaortocaval Paracaval Precaval Retrocaval Retroperitoneal, NOS Spermatic vein Regional lymph nodes, NOS Lymph nodes, NOS **Regional lymph nodes WITH previous scrotal or inguinal surgery** External iliac Inguinal nodes, NOS Deep, NOS Node of Cloquet or Rosenmuller (highest deep inguinal) Superficial (femoral) Pelvic, NOS


Pathologic N Pathologic N Display Description Registrar Notes
pX pNX Regional lymph nodes cannot be assessed Pathologic classification criteria met, evaluation done:
Physician unable to assess N
Surgical resection primary tumor, no regional lymph nodes removed
Involvement of regional lymph nodes not documented
Physician assigns pNX, no other information available to determine N
p0 pN0 No regional lymph node metastasis
p1 pN1 Metastasis with a lymph node mass 2 or less in greatest dimension OR

5 or fewer positive nodes, none more than 2 cm in greatest dimension
Single or multiple nodes not stated, size not stated

Stated as N1
p2 pN2 Metastasis with a lymph node mass more than 2 cm but not more than 5 cm in greatest dimension OR

More than 5 nodes positive, none more than 5 cm in greatest dimension OR

Evidence of extranodal extension of tumor
Single or multiple nodes not stated, size stated and greater than 2 cm but less than or equal to 5 cm

Stated as N2
p3 pN3 Metastasis with a lymph node mass more than 5 cm in greatest dimension Stated as N3
c0 cN0 Clinically: No regional lymph node metastasis Use only for TNM defined pTis cases where there is a resection of the primary and the nodes are not evaluated pathologically
88 88 Not applicable Primary site/histology not TNM defined
Death certificate only (DCO) case
<BLANK> BLANK See Registrar Notes Pathologic classification criteria not met
No surgical resection of primary tumor and there isn’t a positive biopsy of a structure in the highest T category and highest N category
Evidence of metastatic disease (pM1), no other workup
Only Pathologic Stage Group documented (no T, N, or M information available)
